Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveyor technology, and in particular to a lifting conveyor. Background Technology
[0002] A hoist is a vertical conveying device widely used in industrial production, warehousing and logistics, and construction engineering. Its main function is to lift materials or items vertically to a designated height. This equipment typically consists of core components such as a support frame, a hydraulic lifting device, and a lifting seat. The support frame serves as the supporting structure, ensuring the overall stability of the equipment; the hydraulic lifting device is located at the bottom of the support frame and is powered by a hydraulic drive system; the lifting seat moves along the vertical guide rails of the support frame, achieving lifting and lowering motion under the drive of the hydraulic device. Hoists have advantages such as compact structure, stable operation, high load-bearing capacity, and precise positioning, making them particularly suitable for heavy-duty materials and high-frequency lifting environments.
[0003] To improve conveying efficiency, some existing elevators have a lifting conveyor line on the lifting base. During operation, the lifting base moves up and down, and the lifting conveyor line on the lifting base can connect with the infeed conveyor line / outfeed conveyor line to realize the transfer of goods. For example, Chinese Patent Publication No. CN207827131U discloses "an elevator", which has the characteristics of compact structure, small size and low manufacturing cost. It directly connects with the infeed conveyor line / outfeed conveyor line through the lifting conveyor line on the lifting base to realize the transfer of goods, and then realizes the lifting of goods by driving the lifting base to move up and down. The structure is simple and easy to implement.
[0004] However, in actual use, the initial position of the lifting conveyor line on the lifting platform will change after long-term use. When it connects with the feeding conveyor line, a height difference is likely to occur, which can cause the product to roll and fall during the conveying process, resulting in product damage. Utility Model Content
[0005] The purpose of this utility model is to solve the problems existing in the prior art, such as the initial position of the lifting conveyor line on the lifting seat changing after long-term use, and the height difference easily occurring when it connects with the feeding conveyor line, which causes the product to easily roll and fall during the conveying process. Therefore, a lifting conveyor is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a lifting conveyor, including a base and a lifting structure. The lifting structure is provided with a lifting frame, and the lifting frame is provided with a conveying component. A support frame is provided on one side of the base, and a drag chain that cooperates with the conveying component is installed on the support frame. The base is provided with a positioning component that cooperates with the lifting frame.
[0008] The conveying assembly includes multiple rollers rotatably mounted on the lifting frame, and the lifting frame is provided with a drive assembly that is poweredly connected to the multiple rollers.
[0009] Furthermore, the positioning component includes a positioning rod, a support portion is provided on the positioning rod, and a buffer component that cooperates with the support portion is provided inside the positioning rod.
[0010] Furthermore, the buffer assembly includes a pressure plate fixedly mounted on the support portion, a support plate disposed inside the positioning rod, and a spring disposed between the support plate and the pressure plate.
[0011] Furthermore, a screw is threaded onto the positioning rod, the upper end of the screw is in contact with the support plate, and a handwheel is fixedly installed at the lower end of the screw.
[0012] Furthermore, the lifting structure includes a scissor lifting mechanism disposed on the base, and a first motor is disposed on the scissor lifting mechanism.
[0013] Furthermore, the drive assembly includes multiple belts and a second motor, with adjacent rollers being poweredly connected via belts, and the second motor being fixedly mounted on the lifting frame and poweredly connected to at least one of the rollers via belts.
[0014] Furthermore, the lifting frame is provided with a connecting plate, and extension plates are fixedly provided on both sides of the positioning rod. The extension plates are fastened to the connecting plate by bolts, and the lifting frame is provided with a sleeve corresponding to the positioning rod.
[0015] The lifting conveyor proposed in this utility model has the following advantages:
[0016] In this utility model, the initial position of the lifting frame is limited by setting a positioning component, so that the initial position, i.e. the lowest position, is the same after each lifting and lowering, thereby preventing height differences from easily occurring when docking with the feeding conveyor line.
[0017] Secondly, in this invention, a buffer component is provided on the positioning rod of the positioning component to buffer the movement of the lifting frame when it moves down and contacts the support part, thereby reducing the wear of the lifting frame and the support part.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Reference Figures 1-5 A lifting conveyor includes a base 1 and a lifting structure 2. A lifting frame 3 is provided on the lifting structure 2, and a conveying component 4 is provided on the lifting frame 3. A support frame 5 is provided on one side of the base 1. A drag chain 6 that cooperates with the conveying component 4 is installed on the support frame 5. The drag chain 6 is used to install electrical wires. A positioning component 7 that cooperates with the lifting frame 3 is provided on the base 1.
[0026] The conveying assembly 4 includes multiple rollers 41 rotatably mounted on the lifting frame 3, and the lifting frame 3 is provided with a drive assembly 42 that is poweredly connected to the multiple rollers 41.
[0027] In this invention, the initial position of the lifting frame 3 is restricted by the positioning component 7, so that the initial position, i.e. the lowest position, is the same after each lifting and lowering, thereby preventing height differences from easily occurring when docking with the feeding conveyor line.
[0028] Furthermore, in this embodiment, the positioning component 7 includes a positioning rod 71, a support part 72 is provided on the positioning rod 71, and a buffer component 73 is provided inside the positioning rod 71 to cooperate with the support part 72. The support part 72 cooperates with the lifting frame 3 to limit the lowest position of the lifting frame 3, preventing the height of the lowest position from dropping due to long-term use, thereby preventing a height difference when the conveying component 4 is connected to the feeding conveyor line.
[0029] Furthermore, in this embodiment, the buffer assembly 73 includes a pressure plate 731 fixedly disposed on the support part 72, a support plate 732 disposed inside the positioning rod 71, and a spring 733 disposed between the support plate 732 and the pressure plate 731. When the support part 72 is pressed down and moved by the lifting frame 3, the spring 733 is compressed and generates elastic deformation, which buffers the lifting frame 3 and the support part 72. In some embodiments, a cylinder is fixedly disposed on the support plate 732 and inserted into the spring 733. When the support part 72 moves down to a specific position, the pressure plate 731 abuts against the cylinder and stops moving down.
[0030] It should be noted that in this embodiment, a screw 734 is threadedly connected to the positioning rod 71. The upper end of the screw 734 is in contact with the support plate 732, and a handwheel is fixedly installed at the lower end of the screw 734. By rotating the handwheel, the screw 734 can be rotated, thereby adjusting the position of the screw 734 and the support plate 732. This compensates for the loss of elasticity of the spring 733 after long-term use, and can also adjust the lowest position of the lifting frame 3 as needed to improve the applicability.
[0031] Furthermore, in this embodiment, the lifting structure 2 includes a scissor lifting mechanism 21 disposed on the base 1. A first motor 22 is disposed on the scissor lifting mechanism 21, and the scissor lifting mechanism 21 is driven by the first motor 22, thereby controlling the position of the lifting frame 3.
[0032] In detail, in this embodiment, the drive assembly 42 includes multiple belts 421 and a second motor 422. Adjacent rollers 41 are poweredly connected by belts 421. The second motor 422 is fixedly mounted on the lifting frame 3 and poweredly connected to at least one roller 41 by belts 421. The rollers 41 are driven to rotate by the second motor 422 and belts 421, and the multiple rollers 41 are rotated by the belts 421 for conveying products.
[0033] More specifically, in this embodiment, the lifting frame 3 is provided with a connecting plate, and expansion plates are fixedly provided on both sides of the positioning rod 71. The expansion plates and the connecting plate are fastened together by bolts. The positioning rod 71 passes through the expansion plate. The lifting frame 3 is provided with a sleeve that is inserted into the positioning rod 71. The positioning rod 71 can be removed and replaced.
[0034] Working method: During operation, the lifting structure 2 controls the lifting frame 3 and the conveying component 4 to lift and lower. The positioning component 7 restricts the initial position of the lifting frame 3. The support part 72 cooperates with the lifting frame 3 to restrict the lowest position of the lifting frame 3. When the support part 72 is pressed down and moved by the lifting frame 3, the spring 733 is compressed and produces elastic deformation, which buffers the lifting frame 3 and the support part 72.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
